We found this place when looking for a pub showing a hurling match. Its a bar on one side and a reasaurant on the other. It's easy to find - it's in the Matagorda shopping center. (there's not many shops, but plenty of bars and restaurants). We only ate there once and it was reasonably priced and what you'd expect from a pub, but not good enough to entice you back to eat there again, and there's plenty of other restaurants within a stone's throw!
We went back that night, to the pub and enjoyed a Karaoke with Dave, the owner of the place. We were in Matagorda for 12 nights and although we tried other pubs we were drawn back to The Auld Triangle most nights for the Karaoke & craic - and I can't/don't sing. He welcomed everyone, and embarrassed others with good humored slagging - and he can take as much as he gives! It's good entertainment for all the family as Dave gets kids, teens, parents and grandparents up singing.
